In applying to easement window units hinges of the conventional type, it has sometimes been necessary to cut and t each hinge individually,

Th'eisa'shunit'HIV comprisesifaiatfang'le; strap i2 5/` fhav-ing' lveitiali and horizontal portions and an arm 26 extending from the outer angular edge and reinforced by a rib 2'! formed up out of the material of the hinge. This sash unit 2| is secured at the cornerl of the easement sash by means of screws 28 or other suitable fastening devices which additionally secure the vertical and horizontal parts of the sash together.

The frame attachment unit 22 of the hinge has a side frame butt portion 29 and a sill butt portion 30 at right angles to each other and inclined or beveled to t the outwardly beveled surfaces i8 of the sill and the outwardly beveled surface I9 of the brick -mold i5. From these butt portions are extended a shank 3| having upper and lower flanges 32 'and 33 separated at the pivot by the thickness of the arm 26 and the washers 24 at each side thereof, so that the pivot 23 will bind them all tightly together. The shank 3l is shorter than the `arm 26 so that the sash, when closed, will occupy a position inwardly of the brick mold (see Fig. 5). The opposite ends of the flanges are rounded outwardly to join the frame butt portion 29 at a distance from the angular corner, and the lower flange 33 extends to the sill butt portion `adjacent the angular corner between the frame and sill butt portion, thereby greatly strengthening this hinge unit in its pivotal support of the sash. The frame and sill butt portions 29 and 30 may be provided with the usual'countersunk recesses 34 wherein to receive the heads of fastening screws 35 iiush with the proximate surface.

With this construction, the arm 25 of the sash attachment unit fits and swings between the upper and lower flanges 32 and 33 of the shank 3|, thereby providing a neat and trim appearance when the sash is closed. When the sash is swung outwardly from the frame a sufficient clearance is provided for the arm of a person to be extended around to the outside of the sash for washing or cleaning purposes. By inverting these hinges, it is apparent that a single right `and left type of hinge is sucient for mounting and oppositely hinging two sashes in a frame, and that the attachment of the fra-me and sill butts of the hinge in the corner of the frame, strengthens the connection of the parts at this point. If there are f three or more casement sashes to be assembled into a single frame, an intermediate mullion having opposite sides beveled the same as the brick mold will provide a satisfactory mounting to receive the angular butt portions of the hinge which then is attached to the mullion and to the frame at the top and bottom in the same way as already described.

With this construction, each sash and its associate frame is braced and strengthened by the hinges which are simple and easy to apply, as already pointed out. Furthermore, the hinge pivot is exactly located in every case thereby making possible the use of factory prent sashes without danger of the sash hitting the frame or binding therewith as would occur if the pivot point were to vary, as is common when the jamb or sash has to be ychiselled for the hinge, since it is difficult to chisel two hinge mortises alike.

We claim:-

l. A casement sash hinge located in the corner of a casement window frame beyond the outer face of the casement sash and comprising a frame unit fitting within the angle of a corner of said frame exteriorly of the outer face of the sash and consisting of an inner attachment portion secured to the frame and an outwardly eX- tending shank, and a sash unit composed of an inner attachment portion secured to the outer face of the sash at the corner thereof contiguous to the fra-me unit, and an arm extending outwardly from the attachment portion of the sash unit and pivoted to the outer end of the shank of the frame unit and having sufcient length to extend from its pivoted end to the outer face of the sash when the latter is in its closed position to cause the sash in its closing movement to be carried inwardly to a position beyond the frame unit.

2. A casement sash hinge located in the corner of a Casement window frame exteriorly of the outer face of the casement sash and comprising a frame unit tting within the 'angle of a corner of said fra-me exteriorly of the outer face of said sash and consisting of an inner attachment portion secured to the frame :and an outwardly extending shank projecting beyond the frame, and a sash unit composed of an inner attachment portion secured to the outer face of the sash in abutting relation `with theframe unit, and an arm extending outwardly from the inner attachment portion of the sash unit and pivoted at its outer end to the outer end of the shank of the frame unit and havinge. length sucient to extend from its pivoted end to the outer face of the sash when the latter is in its closed position to cause the sash in its closing movement to be carried inwardly to a position beyond the frame unit.

3. A casement sash hinge located in the corner of a casement window frame beyond the outer face of the casement sash and comprising a frame unit tting within the angle of a corner of said frame beyond the outer face of the casement sash and consisting of a vertical side frame butt portion and a horizontal sill butt Vportion arranged at right angles to each other and inclined to t an outwardly beveled vertical portion of the frame and the beveled surface of the sill of said frame, and a shank extending outwardly from said butt portions, and a sash unit having a nat angle strap secured to the outer face of the sash at the corner thereof adjacent theframe unit and provided with an outwardly extending armpivoted to the outer end of the shank of the frame' unit, and having a length sulcient to Vextend from its pivoted end to the outer face of the sash when the latter is in its closed position to cause the sash in its closing movement to be carriedk in-y wardly to a position beyond the frame unit.
